Alright, I just got in my MTK armor and had an issue on return edges. I watch Mikes videos, he cuts the armor where there is no return edge left, however I see numerous individuals here creating them. One, is it mandatory to have a retun edge and what are the benefits and downsides to a retun edge. Also, my armor needs much trimming. Could I not just leave a few millimeter lip on the trimming to work as a return edge? Thanks guys and sorry about simpleton questions!
